Heh heh... yeah, it's a lot of info and I don't have the exact ratios, but as explained to me, it works a little like this:
Your top pre-93 hires are on top and untouched.
Our #1 guy starts just below them and it's ratio'd pretty evenly for the '93 hires and our senior CA's (I don't know how many), but we end up with the top half of our CA's ratio'd in with your post-'93 CA's.
The next half of our CA's get ratio'd in with your top F/O's.
The top 150 of our F/O's get ratio'd in with your BOTTOM F/O's.
The remaining 650 AAI F/O's get stapled to the bottom of the pre-9/27 list, starting about year 6 F/O for us and lower.
Your post-9/27 new-hires are stapled below them. Our post-9/27 new hires are stapled at the very bottom.
Those are VERY rough numbers, but present a good broad picture of how it went. The average seniority gain on a combined list on the SWA side is 6%, the average seniority loss on the AAI side is 22%, with spikes among our senior CA's (up to 35%) and senior F/O's (up to 28% - mine is a 26% relative seniority loss).
edit: my first post said our "least amount" of seniority loss was 22%. It's not, that's the AVERAGE seniority loss. They said something about our mid-level CA's take the smallest loss, but I don't remember the exact number, sorry.
